In another sign that the U.S. economy is doing well, officials at the Port of Los Angeles and the nearby Port of Long Beach, Calif., said February was a record month for shipping goods in and out of the biggest ports in the United States.

The average time to enter and exit the two largest containerports in the United States slowed one minute in January on a year-over-year basis, although the percentage of trips over two hours fell in the same period.

The Port of Long Beach recovered from a rocky 2016 with a record-setting year in 2017, moving 7.5 million industry-standard twenty-foot-equivalent units, the port’s leader announced at the State of the Port address Jan. 24.

Truck drivers took one minute longer, on average, to enter and exit the two large ports in Southern California in December 2017 compared with the same month in 2016, although the full-year average was three minutes faster than a year ago.

The average time it took a truck driver to enter and exit the two largest ports in North America — Los Angeles and Long Beach — was 10 minutes quicker in November versus the same time a year ago, according to the Harbor Trucking Association.

The average time it took a truck driver to enter and exit the major Southern California ports fell 7 minutes in October on a year-over-year basis, according to monthly data from the Harbor Trucking Association.
